Patent GB-492599-A (GB)
Title: Improvements in and relating to the isolation of zein
IPC: C08L89/00
Filed: 1937-03-18
Abstract: Zein is extracted from proteinaceous material derived from maize by means of an aqueous alcoholic solvent at a temperature not above 70 DEG  C. and a hydrogen ion concentration such that the pH of the final extract is not less than 6.  The solvent may contain up to 20 per cent or more, preferably 7-8 per cent, of water and may be pure aqueous ethyl or methyl alcohol or mixtures with other organic solvents.  Extraction is preferably effected at 55-65 DEG  C., the final pH being 6 to 7.  Gluten meal may be extracted with 93 per cent alcohol.  The pH value, which is normally too low and, moreover, falls as the extraction proceeds, is regulated by the addition of alkali such as sodium hydroxide at the beginning or from time to time during the extraction.  The extract may be concentrated by vacuum distillation, for example to 30 per cent zein content.  It is treated with a solvent for oil and colouring matter such as toluol, benzol, xylol, carbon tetrachloride or, less desirably, aliphatic hydrocarbons such as petroleum ether, and the solvent layer separated.  The zein solution is mixed with water to precipitate the zein which is mixed with water until it loses its adhesive nature, rolled into sheets, soaked in water and dried.  The dried sheets can then be ground for use in making plastics.

Title: Improvements in the manufacture and production of artificial threads
IPC: D01F2/30
Filed: 1928-10-04
Abstract: 327,737. Johnson, J. Y., (I. G. Farbeninindustrie Akt.-Ges.). Oct. 4, 1928. Divided on 327,671. Right to Patent relinquished. Cellulose esters and ethers, processes for making filaments from; apparatus for making filaments.-Dry-spun artificial threads prepared from cellulose acetates or other carboxylates or from cellulose ethers, and having a tensile strength higher than the normal, are obtained by employing spinning nozzles of glass, quartz glass, or similar vitreous material the length of the bore of which is five or more times the diameter, preferably ten times or more, and by stretching the filaments immediately on extrusion to five or more times their original length. The fining of the filaments is stated to be possible because of the more or less perfect orientation of the cellulosic particles that occurs during the passage of the solution through the elongated nozzles. In examples, solutions of cellulose acetate or ethyl cellulose are spun through glass nozzles having the following length and diameter dimensions :- 1.0 : 0.1 mm., 3.0 : :0.1 mm. and 2.0 : 0.08 mm.; and the filaments are stretched to 5, 10 or 20 times their original length. Specification 198,023 is referred to.

Title: Improved escapement mechanism, especially for toys
IPC: A63H11/06
Filed: 1954-03-19
Abstract: 760,147. Toys including escapement mechanisms. TIGRETT ENTERPRISES, Inc. March 19, 1954 [April 30, 1953], No. 8088/54. Class 132(3). An escapement mechanism especially for use in toys utilizes a means capable of temporary adherence to a reaction surface as the timing device in the mechanism. In Fig. 1, arms 51 of a rotor 50 rotatable clockwise by a windable spring (not shown) are engageable with arms 25a, 26 of a pallet 22 provided with a suction cup which coacts with a roughened surface 27. In operation of the device, a rotor arm 51 engages pallet arm 26 and thus urges the suction cup into engagement with the surface 27. After sufficient air has leaked into the interior of the suction cup, the cup moves upwardly as a result of the pallet arm 25a being engaged by the next succeeding rotor arm 51 which then moves into engagement with the pallet arm 26 and the cycle of movements is repeated. Fig. 4 shows a toy fish in which the ends of a single-arm rotor 116 may extend through slots 144, 145, intermittent rotation of the rotor arm causing the toy to jump when resting on a surface and simulate a landed fish. In Fig. 6 (not shown), the arms of a six-armed rotor serve as " feet " of a toy bird which is propelled in a hopping manner. A " jumping bean" embodiment, Fig. 7 (not shown), has a single-arm rotor only one end of which is engageable with the pallet arms. In Fig. 8, intermittent engagement of a suction cup 190 and a surface 196 is caused when an arm 195 rotating clockwise engages in turn faces 193, 194, thus producing a reciprocating action of a yoke 191. In Figs. 12, 13 (not shown), a single arm pallet is provided with a cam surface which is engageable by the ends of the rotor arms. Alternative means to provide an imperfect seal of the suction cup and the coacting surface comprise leakage passages in the cup or the coacting surface and roughening the engaging surfaces of the cup and reaction surface. Pressure sensitive adhesive material may be used in place of a suction cup.

Title: Electronic phase-splitting devices and frequency discriminators
IPC: H01J21/14
Filed: 1945-03-30
Abstract: 607,771. Frequency mediation. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. March 30, 1945, No. 8115. Convention date, April 3, 1944. [Class 40 (v)] [Also in Group XL (a)] A phase-splitting discharge device comprises a cathode 11, Fig. 1, for producing two streams of electrons modulated in intensity in accordance with a high - frequency carrier wave modulated in angular velocity, i.e. frequency or phase modulated, and collecting means arranged so that the transit times of the two electron streams are substantially different, e.g. by an odd number of half-cycles of the carrier wave. The outputs may be combined at the collecting means, which may be a single electrode 13, Fig. 1, or two secondary emissive electrodes which may or may not be structurally separate plus a common collector, Fig. 4 (not shown); the device is then used for frequency discrimination, the output being amplitude modulated, the modulation corresponding to the frequency deviations of the input signal. Alternatively, the outputs may be taken off separately, Fig. 5, at electrodes 40, 41, with or without secondary emissive electrodes 20, 21 in which case they may be combined outside the tube. One beam path may be lengthened relatively to the other by the use of a magnetic field. The carrier is modulated by sound, video, or code and at the receiver is fed into a converter 2, Fig. 1, which is also supplied with local oscillations from the oscillator 3; the converter 2 is however optional. 4 is an amplifier and 5 an amplitude limiter. The modulated signal energy is then applied to the discharge device via the control grid 12. The discharge device is of the orbital beam type, having cylindrical focusing electrodes 9, 10. The cathode 11 is hollow and of rectangular cross-section and contains a heater. A screen may be placed around the collector 13, and a screen grid may be placed around the control grid, Fig. 3 (not shown).
